.To all whom may oofzvcerni;

Be itltY nown that we,ENoen M. GoRDoN, J or ATHAN S. GORDON, and WILLIAM H. GORDON,

' pulleys, r/ la.

ot' NVOodStoelt, in the county of Grafton and State of, New Hampshire, have invented eer-- tai n new and useful Improvements in Machinery for Making Potato-Starch, 'and we do herevby declare .that -the same are fully described .2 is a side elevation of it. p Fig. `3 is ai cent-ral longitudinal and vertical section, of it.

In'said drawings, lArf denotes the'main framework, constructed in any proper manner so asto sustain the operative parts of the machine to be described.

.A and B are two raspingeylinders, each of which consists of af/wooden drum covered'on its curved surface withsh eet metal' made rough by punelrholes so made through it as to leave thei r burrs proj eetin g from its external curved surla'ee. Above the first orupper rasping-oyl inder, A, is a hopper, C', and a supplying waterv fountain kor Vreservoir, D, through the bottom of which reservoir is a long slit or'suitable aperture, a, for the-purpose of allowing water to pass in a thin sheet or moderate stream into the hopper in order to' prevent the surfaces of the rasping-eylinders from getting foul with..

ibrons matter. In front oi' the upper raspingcylinder are two gagebars, E F, which are dis; posed as seen in the drawings. Each of them should have wedges or Aother `suitable contrivanees adapted-to it, so as to enable it to be advanced toward the raspingsuriaee of the cylinder as near as it maybe necessary. The

lower cylinder, B, also lhas'two such gage-bars G H, which 'are similarly applied to it, and are arrangedas seen in Figs. 2, 3. A shrouding or ease, I, is made to surround thetwo raspingcylinders. It has a long slit or opening, b, made through the bottom or' lower part of' it, the same being to allow the 'pulp to-pass out of the ease and fall upon-a sieve, K, arranged underneath it, and vibrated horizontally with a quick reeiproeating hnotion .by means of a crank-shaft, L, which` is .supported in bearings in the tops of standards N N, and -has two belljointed to the t'frauksand the 'frame On one end of 'said s'haft are two "lhere are also two pulleys, ./i 7c', ofthe shalt ofthe lower raspspeeti vely ofthe sieve.

on the near end finge Tlind'er. There. is also'an'other pulley, `l,

on its opposite end, and pulleys m and .on the two ends of the shat't of the upper rasplugeylinder. The vdriviu; ;'-1 ow.er is applied lto the pulleyvz.. An endless belt, of, passes around the 'two pulleys mv and I and communieatpsmotion to thelower cylinder and its shaft, whielralso, Aby means ot' another endless belt, p', made to pass around both ot' the pulleys f/ and 'i or l:

-and lf, puts the eraukfshaft in motion, so as to v operate the sieve.

D is a trough, wliiehis supported by'and made movable on the top mila-'(91), oft-he frame at A oi" the machine. Said trough has a grt.

number of small holesinade through its bottom, yin order to allow water poured into the trough to descend in a shower or spray upon the sieve beneathit. Said trough should be sustained uponthe rails o 1) in Such manner as to the upper cylinder in order to cause thshower of water proceeding from Ait (the trough) to be equally distributed upon the whole-surface of the sieve should the same be necessary. der the sieve is a shallow-reservoir or vat, Q, which, by means` of a' spout', lh'eomniunieates with a transverse distiiluiting-trough, S, raised above a largeand shallow cistern or Vt t, R, seen in the drawings. The said vat It is 'divided into two or more compariments, T U, by one or more'eross'-partitions, as seen. at V.

lt should be about sixteen or' eighteen feet square and a foot deep for a stream that flows /iut'o it at t he rate of twenty ga'llons'llcr minute, The said partition or partitions V may be au inch or two higher than that side of the vat" overwhieh the liquid is to tlow in a thin sl1eet.

This however, will crt-ate a st roneer current,.

ery-is as follows: `The rasping-oylinders being' putinrevolution andi he hopper iille'd with po tatoes, the said potatoes will be ra'sped or re duced to a pulp by thegaetion of the two cylinbe capable of being moved toward or from ,I

ders and'tlieir gage-bars. The said pulp after passing o ut of the lease or shro'uding ofthe cylinders is 'received upon the sieve beneath them,

the motion of Vwhich causes the 4pulp to be dis- 'tributed over its surface. The shower of water which falls on the .pulp-separates the starch V from the mass and carries it throughthe sieve` into the vat below it.

From the said vat the combined liquor,'and starch flow into the distributing-troughs of the settlingwatR. -The starchy liquid spreads out throughthe trough Iand passes in a thin sheet over the side of the same, (which may beproperly formed or cut .down so Vas toadmit of the same,) orthrougj-fh a long slot, av, made through the said side. It 1s received into' the adjacent compartment T "of thesettling-vaa'which it will fill to thelevel .Ofthetop of the., partition "V, and will then iiow `over 'said partition'and into the next coini partinent until 'it is also' lled. The liquor is.draiinig'..pumpedoif or removed andthe starchzafterward'taken out. e gfg-Qhefdiiei'ence between ormode of opeating and thatheretofoie inyus'ef'will be readily seen. By our apparatus we are able to' main'- Vtain aI constant or continued operation, Where- -as by the Vuse of a deep vatin the manner' as heretofore practiced th ewater lnu st'be su fercd to remain quiet for some length of time before it can bedrawn oi' and the sta'rehfi'cmoved. z

In our apparatus,'as our vat is shallow-or 'about one foot indepth, we can readily gain access to the deposited starch so as tourelnove it as fast as it 'may be necessary.

By usingthe aforesaid eombin'ationof -two rasping-cylinders and their` gages oigagebars we are enabled to produce much better pulp.

than can be made bythe old single rasping` machines.V

YVe' therefore clainn- 1. The distributing-trough s, :isA combined withthesubsidingrvatB', and vat Q, and used.

inthe manner and for the purpose substantially :as-specified'. .f

2. Our improvement of usingia shallow sub- `sidingvat in the mannerand forthe' purpose substantial'lya's described,` instead,4 of usinga deep 'one as heretofore employed..
